This article reviews application field and working principle of IXD3236A12CMR-G, a DC DC switching regulator.

Background

IXD3236A12CMR-G is a DC DC switcher designed to deliver up to 36A Iout with good efficiency. It is a synchronous rectifier PWM buck converter with an integrated gate drive circuit for the synchronous MOSFETs. The classic "ready" solution of this model provides a simple and effective solution for high current step-down applications.

Application Field

As a widely used DC DC converter, IXD3236A12CMR-G has many application fields, such as telecommunications and industrial equipment, LCD displays, notebooks, memory,and storage apparatus. Its high reliability, wide output voltage range and low power consumption make it ideal for these types of applications.

Working Principle

IXD3236A12CMR-G works through a process called ‘pulse-width-modulation’, which is a form of variable-duty-cycle control. In this process, the peak current is regulated by varying the duty cycle of the switching waveform. When the switch transistor is "on", the output current is supplied to the load capacitor and then start to decline. When the switch transistor is "off", the load capacitor will start to recharge with the current supplied by the input voltage.

The output voltage is sensed and compared to a reference voltage set. The amplifier then amplifies the voltage difference and provides a signal to pulse-width-modulated switching transistor. When the current of the output starts to decline, the comparator senses the output voltage and the switching transistor will later turn on for a longer time. This continuous process enables IXD3236A12CMR-G to deliver DC voltage with adjustable current levels defined by the duty cycle.

Conclusion

IXD3236A12CMR-G is a DC DC switching regulator designed to deliver up to 36A Iout with excellent efficiency. It is an ideal solution for high current step-down applications in a variety of applications. The working principle involves a pulse-width-modulation process that regulates the peak current by varying the duty cycle of the switching waveform.
